if 13...,.-. .ND .Moderated Application filed October 16, P318.

To all whom it may concern Be it known that l, JAMES H. Pusan, `a citizen ofthe United States, resident of Innes, Province of Saskatchei "an, Dominion of Canada, have invented certain new and useful improvements in Shockers, of which the following is a specification. Y

rlhe object of my invention is to provide an attachment for a binder, of'simple construction and comparatively ylight draft, which Will receivethe'bundles ofgrain from the binder in, any number desired and when a suiiicient vnumber has been collected, deposit them upon the ground in the form of a shock.

A further object isto provide a shock of such construction that the tops `of the bundles will be pressed together and the butts separated to such an extent that all danger of the bundles or the shock toppling over when placed upon the ground ivill be avoided and Without the use of twine or other shock bindingnieans.

@ther objects of the invention Will appear from the following detailed description.

'.lhe invention consists generally in various constructions and combinations, all as hereinafter described and particularly pointed out in the claims.

Serial No. 125,964.

Fig. 11 is a detail view of the cable and pulley, through the operation of which the bundle pans are tilted.

`ln the drawing, 2 represents a side portion of a grain binder of ordinary construe# tion. 3 is a draft connection, secured to the under side of the `binder by suitable means, such as Ushaped clamps e. This draft connection 3 projects laterally beyond the binder and has a pivotal connection at 5 with the forward end of a pole 6 that is connected-to a suitable axle/Tandprovided with brace rods 8. The axle has carrying Wheels 9 and 10, the latter provided With traction pins or studs 11. `The draft connection 3 and the pole 6 `may be made of any suitable material, metal or Wood, as preferred.

The pivotal connection of the shocker With the binder is preferably in line With the axis of the bull and grain Wheels, as indicated in Figs. 1, 5 and S.

T he draft connection, as shown in Fig. 2, is preferably vlil-shaped in form and supports a frame 172 secured thereto. A shaft 13 is mounted in the frame 12 and carries a ratchet Wheel 14 having peripheral -teeth 15 (see Figs. 4C, 9 and 10) and a series of pins 16 mounted in one face opposite and adjacent the shoulders of the teeth 15. An arm 1T is loosely mounted on the shaft 13 and projects upwardly through a slot 18 in the deck 19 of the binder and in the path of one of the kicker arms 2O to be actuated thereby. rThe arm 1T has a dog 21 that is normally held against the teeth 15 by the tension of a spring 22 and when the arm 17 is struck by the kicker and pushed to the position indicated by dotted lines in Fig. 10, the dog 2l will slide over the teeth of the ratchet and ivhen the arm is disengaged from the kicker the spring .22 will ret-urn the arm to its normal position and reyolsfe the ratchet Wheel. A shaft lis mounted in bearings adjacent to the lower end of the deck and is provided on one end With a division board 2i and on its opposite end With a Wing or lug 25 which `projects into the path of the pin 16 to be actuated thereby for the purpose of rocking the shaft 23 to raise the division board, as Will hereinafter appear.

A standard 26 is .mounted on the middle portion of the pole 6 and projects upwardly therefrom and has a bearing at its upper end for a. shaft 27 having hubs 28 and 29 mounted thereon. (See Figs. 1, 3, 5, and 11.) Arms 30 and 31 are secured at one end respectively in said hubs and project forwardly and downwardly therefrom and support pans 32 and 33 having vertical pivots at 34 on said arms to rock in a horizontal plane, being normally held in alinement with said arms by springs 35. (See Fig. 1.) The purpose of having these pans oscillate is to allow them to be alined with` the end of the binder deck in positionto receive the bundles therefrom, while permitting the rear portion of the shocker to swing inwardly toward the binder or outwardly therefrom, as in turning.

l do not wish to be confined to the number of pans shown herein or the manner of mounting the same, as l may find one pan to be more suitable for the purpose than two, and l may wish to mount the pan to compensate for the adjustment of the binder. In the construction herein shown, I have provided the pan 32, or the one adjacent to the binder deck, with slots 36 to,

receive projections 37 which are mounted on the deck and extend outwardly there-l from on each side of the opening 18. These extensions receive the bundles and guide the foremostvone over the first bundle ypan upon the second one. The pans have spurs 37 thereon for engaging the bundles and thev pan 32 has points or projections 38 which engage the wild mustard or any weed that may be clinging to the binder and tear it loose. (See Fig. 7.)

l prefer also to provide a guide 69 near the normal position of the pans for engaging theedges thereof and directing them to their normal, receiving position in aline- `ment with the end of the binder deck and against, if necessary, the tension of the springs 35. This function of the guide G9 as in the act of turning or when the vbinder and shocker are not in the relative position shown in Fig. 1.

T he packer arm of the binder is indicated in dotted lines in the figures (6 and 7) and against this arm the grain is packed until a predetermined point is reached, when the packer arm is withdrawn and the kicker operates to discharge the bundle off the deck. rFhe first bundle, as indicated in Fig. G, slides over the extensions 37 and drops upon the pan 33, the division board 24 then being in its lowered or normal position, as shown in Fig. 5. As soon as the kicker passes out of engagement with the arm 17, the spring 22 will return this arm to its raised position and rock the ratchet wheel 14 and cause one of the pins 16 to engage the wing or lug 25 and rock the shaft 23 sufliciently to raise the division board 24 to the pointindicated in Fig. 7, where it will be between the two pans and in the path of the second bundle. The division board will remain in this position while the arm 17 is being moved again by the kicker to the dotted line position shown in Fig. 10, but on the return of the arm 17 after the discharge of the second bundle from the deck, the pin in engagement with the wing 25 will be moved sufhciently to clear this wing and allow the shaft 23 to rock and the vdivision board 24 to swing down to its normal position below the level of the pans. At this time one of the pins 16 will contact with a trip lever 39 mounted at 40 and having a flexible connection 41 around a double pulley 42 (Fig. 2) with a rocking clutch arm 43 which controls the movement of a clutch 44 for temporarily locking a cam 45 on the axle 7. A lever is pivoted at 47 and has one end bearing on the cam 45 and is connected at lits other end through a cable 48 with the periphery of a pulley 49 on the shaft 27 for rocking Vthe said shaft and raising the arms 30 and 31 from their` normal position, shown in Fig. 1, to an inverted position for discharging the bundles into the `shocker basket at the rear of the machine, as indicated in F ig. 5. Instead of operating the trip lever through the movement of the pins 16, l may actuate it from some other moving part of the machine, such as the needle.

The cable 48 has an extension spring 50 therein which is put under tension when the lever 4G is oscillated to tilt the bundle pans to their discharging position to pack the bundles inthe s ocker basket and also to offer a yielding resistance to the return of the pans to their normal position Aand pre` vent them from striking their support with a jar or shock, which might result if the .pans were allowed to fall back to their normal receiving position through their own weight. A. disk 45 is mounted to revolve with the cam 45 and the clutch arm 43 rides on the edge of this disk and is held thereby in position to keep the clutch members in engagement with one another until the said arm reaches a depression or recessv4 provided in the edge of said disk, and upon entering this depression a spring 46 will return the clutch arm and clutch connected therewith to their normal, inactive position and allow the bundle pans to remain stationary until they are again filled and the clutch again engaged.

A smaller pulley 51 is mounted on the shaft 27 and a cable 52 is attached thereto and to an extension spring 53 which is put under tension when the pans are tilted from the position shown in full lines in Fig. 5 to the dotted line position in the same figure. When the cam 45 has revolved a suflicient distance to relieve the pressure of the lever 46, thetension of kthe spring 50 will be relaxed `and the spring 53 will then swing the empty pans back to their normal position, the spring 50 exerting sufficient pull on the cable a8 to retard the descent of the pans and cause them to drop gently upon their support in position to receivel another pairot bundles from the binder.

In the rearfot theaxle is a trame 54 ot' suitable material, having shoes 55 which have a. hinged connection with the aXle through links 5G. (See Figs. Q and 3.) This frame supports the basket to which the bundles are delivered by the tilting pans. rllhe basket normally occupies the raised position indicated in Fig. 5 and is provided with `walls 57 having inwardly turned ends 58 at the front ofthe basket. The side rails 54a of the trame 54 have laterally projecting portions 54:1) arranged to telescope in the 'forward end rail 5ta, as shown in Figs. l andQ, to allow the walls of the basket to be adjusted toward or from each other to decrease or increase the width of the basket and its bundle capacity. rllhe .iframe also has .a central rail 59and an arched rail 60 above it, on which wings 6l are hinged. A sleeve 62 is mounted on. the rail 59 and links 63 pivotally connect it with the lower portions of the wings 6l to allow the lower edges ot' the wings tobe spread apart and drawn together to adapt them tor the varying widths of the basket. rllhe wings are also tapered from their forward toward their rear ends to allow them to be easily withdrawn from the shock when the basket is tilted down to a horizontal position to discharge its contents. The shoes 55, as shown in Figs. 2 and 3, project under the walls oithe basket and rest upon the ground when the basket is tilted down to its dumping position. rllhe links 56 at the forward end of the shockerbasket have the 'function-olf allowing the basket to tilt or ride upwardly at its forward end when it strikes an obstruction, or sway from side to side to clear any obstacle when the basket is in its horizontal discharging position and is being drawn along during such discharge. This manner oi mounting the basket have `found to be an important feature ot my invention.

A rod 64 connects the forward portion of the basket with one end of a lever 65 which is centrally pivoted at 66 on kthe standard 26 and the connection of the rod Glwith the lever is normally in advance ot the center of the pivot 66 and is held in this position by the tension ot a spring 67 which connects the lever 65 with the forward portion of the frame. This rod permits the lateral oscillation or rocking of the basket to accommodate itselt' to irregularities ot the ground over which it may be moving when dropped to its discharging' position, The

basket willremain in the position shown in Fig. 5 until the desired number of bundles have `been placed therein to eform a shock, and at this time the driver of the machine, through the cable 68 attached to the lower end of the lever 65, and passing aroundthe double pulley 4t2 and from thence to a point inthe drivers seat, `may tilt this lever on its pivot and allow the 'basket with the bundles therein to drop down to its horizontal discharging position. The dotted line position of the pans in Fig. 5 indicates the stroke of the pans when vthe basket is nearly full ofbundles. It will be understood, however, that when the iirst bundles are discharged, the pans will swing down nearer the forward end ot the basket and thebundles will be laid in a substantially horizontal position therein, one above another, upon each side of the spreaderh and as these bundles are laid in the basket, their butt ends will `be separated by the spreader a sufiicient` distance to `insure ythe shock assuming and remaining in an upright position when the basket is illed and dropped down to discharge :the shock.

The walls olf-the basket are so formed, as indicated in Fig. 5, that the first bundles deposited will assume a backwardly and downwardly inclined position therein, the tops of the bundles being pressed together as they are discharged from the pans and the straws of one bundle allowed to intermingle with those of the adjacent bundles, while the butts are spread apart or separated so that when the basket load is deposited uponthe ground, the shock will assume and remain in anupright position andthe basket may be withdrawn from engagement therewith without danger of the shock or any of the bundles toppling over.

lWhen the basket has discharged its contents, the driver will release the cable 68 and the tension of the spring 67 will return the `lever 65 toits normal `position and raise the basket to its substantially upright or illingposition, ready to receive anothersupply of bundles from the pans.

rlhe operation ot the machine vis as follows: rEhe first bundle isdelivered upon the bundle pan remote from the deck of the binder, assuming that two pans are used. The ldivision board is then raised and-the secondbundle delivered to the adjacent pan, and at this time `the ratchet mechanism will throw the clutch on the axle and set the mechanism in operation for tilting the bundle pans to van inverted position and discharging the bundles into theraised shocker basket, wherein the bundles will lie, one upon the other, with their heads or tops compressed and interwoven, while the butts will be loose and spread apart. rllhis will follow from the general shape of the walls ot the basket and the spreader interposed llO between the walls, as hereinbefore specificallydescribed. The pans will then be returned to their receiving position and the operation will be repeated until the basket is filled with bundles or until the desired number for a shock has been placed therein. The driver will then trip the basket and drop it to its horizontal discharging position, the butt ends of the bundles will strike upon the ground and, as the machine moves along, the basket will be withdrawn from engagement with the bundles, leaving them in an upright position in the form of a shock and the tops of the bundles being pressed together and the butts loose and spread apart, there will be nodanger of the shock falling over when the supporting walls of the basket are withdrawn. rlhe basket illing operation will immediately be resumed and con-v tinued until the basket is filled again.

l do not wish to be confined in this application to the mechanism shown for controlling the movement of the pans or the shocker basket, or the manner of tripping the mechanism for operating the pans,as in various ways these details of construction may be modiiied and still be within the scope of my invention.
